RAZOR.

ag nt-ea March'12, i907.

- To all whom it may concern:

Be a known that n m. W. GAGE, a resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Safety-Razors, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates't'o safety-razors, is an improvement upon the invention shown and described in the Letters latent No. 7 65,885,

granted to me July 26, 1904, and it consists in certain novel features of construction,-arrangement, and combination of parts which will be readily understood by reference to the description of the accompanying drawings and to the claims to be hereinafter given and in which my invention is clearly pointed out.

Of the drawings, Figure -1 represents an elevation of one side of a safety-razor embodying my invention. Fig. 2 represents an enlarged transverse section of the same on line 2 2 on Fig. 1. Fig. 3 represents an elevation of the inner face of the toothed bladeclamping plate. Fig. 4 represents an enlarged. transverse section of the same on line 4 4 on Fig. 3 looking toward the top of said figure. "rig 5 represents an elevationof the inner face of the other clamping-plate. Fig. 6 represents an enlarged transverse section of the Same on line 6 6 on Fig. 5 looking toward the top of said figure. Fig.7 represents alongitudinal section on line 7 7-on Fig. 5. Fig. 8 represents an elevation of the tubular handle, partially broken, in section. Fig. 9 represents an end view of'the same. I Figs. 10 and 11 represent, respectively, an eleva tion and an enlarged end view'of the razorblade. 'Figs. 12 and 13 represent, respectively, an inside elevation and an enlarged plan of a supplementary plate to be used in lieu of the toothed clamping-plate to hold the blades when stropping the same and Fig. 14 represents an enlarged transverse section of the two cutting-blades clamped between the plates shown 1n Figs. 5 and 12 preparae tory to stropping the same. 1

Similar characters designate like parts throughout the several figures of the drawm s. r

' n the drawings, l-isa nard or back plate, which is provided on eac edgewith a series of teeth 2. This plate is cut from sheet metal and has swaged in its inner face .a longitudinal groove 3, a cross section of which may be semihexagonal, semioctagonal,

or have a fiat bottom and'inclined sides, as shown in Figs. 2 and 4. One end of the plate. 1 has a narrow strap-like portion 4, swaged in the opposite direction to the grooved portion 3,-thereby forminga stirrup adapted to cooperate with a tenon or tongue 5 in the upper end of a clampingplate 6 for the purpose of locking the outer ends of said two plates together. The guard or back plate 1 and the clamping-plate 6 00-;

operate to clamp in position 'two razorblades 7 7, each of which is provided at each end with a notch 8, located substantially contrally of its two edges, as shown in Fig. 10. The end portions of 1 the stirrup 4 on the guard-plate 1 enter the notches in the upper ends of the blades 7 7 to position said blades. The plate 6 also has swaged in its inner face the longitudinal groove 9, having a flat bottom and inclined sides similar to that in. the

plate 1, and is provided at its upper end wit the before-mentioned tongue 5, While intermediate of its ends are two holes 10 10,

formed therein in positions to register with the notches '8 in the lower end of the razorblades when said blades are placed in their proper positions between said clampingplates 1 and 6, the plate 1 having set therein and projecting from its inner face the two ins 11 1 1, which engage the notches Sin the lbwer ends of the razor-blades and enter the holes 10 in the plate 6. It is obvious, therefore, that by means of the notches 8 in the ends of the blades cooperating with the stirrup 4 and the pins 11 the blades 7 are prevented from movementin either direction.

' The plates 1 and 6 terminate at their lower ends in the shanks-12 and 1 3, respectively,

which may be semihexagonal, semioctagonal, or of such shape in cross-section as to fit closely the .innerperimeter of the tubular handle 14 when said two shanks are united by placing said plates 1 and 6 together in as-- sembling the parts. By this means, with the upper ends of the plates 1 and 6 locked together by means of thetongue 5 and the stirrup 4 and the lower shanks are united and inserted in the tubular handle 14, the blades 7 7 will be securely clamped between said plates. The exterior of the handle 14 is preferably many sided for the purpose of enabling the.

user to get' a firm grip thereon and a better control ofthe position of the razor. The inner faces of the plates 1 and 6 have their-flat portions on opposite sides of the grooves 3 and 9 in different but parallel planes, the dis- II) I tance between said planes being just equal to the thickness of a: razor-blade, so that said blades may overlap each other and'the rear of each of said blades have a backingof an 5 inner wall of'one of said grooves 3 or 9, as shown in Fig. 2.

A safety-razor constructed according to this invention may be producedat a comparatively small cost, is convenient for use, and

1 may be' used a long time without shar ening, as it has two inde end'ent cuttin -bla es.

- The 'ofisets in t e platesl an 6 for forma ing the grooves-3 and 9 are mainly; for! the purpose of. stiifenin said plates wit out materially increasing t eir weight, while-at the same time they offer a rea y abutment for the rear edge ofeach of said plates to more readily osition the same.

For t e purpose'of facilitatin the strop 2o ping of the razor-blades a thir clampinglate 1'5(shown; in Figs. 12, 13, andfll4) 1s rnished with eachrazor, saicLplate beingan exact duplicate of the plate 1,, except that it has no guard teeth, its width being ust equal tothe distance between the bottoms of thetwo rows of teeth, and has'its longitudinal edge portions'beveled on its outer side the:

same as the Fig. 6. Having thus' describedmy invention, I
